New dome for Saints home
High-performance polyurethane materials marched into service in fast track restoration of resurrected New Orleans stadium roof

Tens of thousands of people were taking refuge inside the Louisiana Superdome on Monday morning, Aug. 29, 2005, when winds from Hurricane Katrina sheared away much of the roof’s covering, allowing water to leak into the stadium. By mid-October, crews from Brazos Urethane Inc. were working on the Superdome’s 9.7-acre roof to repair and temporarily waterproof the Superdome so that renovations could begin on the interior. The contract required the work to be finished in 45 days; however, the 30-man crew accomplished it in 15 days, earning Brazos Urethane a substantial bonus for finishing early.



“Before the job was bid, I knew there was a very short timeline,” says Wally Scoggins, owner and president of Brazos Urethane, Texas City, TX. “There was a $20,000 a day penalty for going over 45 days, manent new roof, which is scheduled to be completed by September 2006.
The materials specified for the job were a polyurethane foam/
polyurethane coating system supplied by Bay Systems North America LLC, a subsidiary of Bayer MaterialScience, and Neogard, a division of Dallas-based Jones-Blair Co. Before bidding the fast-track job,
Scoggins geared up with the purchase of four Graco/Gusmer H-20/35
Proportioners for the foam and coating application, 2,000 feet of hose, 10
Graco 5:1 drum pumps, and four Xtreme® pumps.
“I already had enough equipment to do the dome, but I bought all new
equipment because I wanted to be confident that we’d have no
equipment or maintenance issues whatsoever,” Scoggins says.

A concrete business in Nebraska recently re-covered its metal flat roof with spray polyurethane foam and saw an average 63% decrease in its utility bills through decreased energy usage in heating and cooling. Energy reductions such as this will reduce the usage of fossil fuels that are used to make electricity, thereby reducing carbon emissions.


A Demand for Green Products
Architects, builders, and owners are creating a revolution in the way new buildings are constructed. This revolution is green building, and has generated demand for a sustainable roofing system that supports energy awareness and conservation.
Effective green building can lead to reduced carbon emissions and reduced environmental impact. The Bayseal™ Spray Polyurethane Foam (SPF) Insulation Roofing System manufactured by BaySystems contributes to the green building movement by providing products that can help positively impact the environment.


Conserve Energy
A roof made of Bayseal spray polyurethane foam roofing insulation and Bayblock protective coatings controls both heat loss and heat gain through insulating, reflecting solar radiation, and emitting thermal radiation. This reduces roof temperature extremes, thereby reducing the energy used to cool and heat the structure.

Decrease Urban Heat Islands
Dark buildings and pavement in cities absorb more of the sun’s heat during the day and release it at night. This creates the urban heat island effect which results in increased air-conditioning costs, energy use, and pollution. BaySystems’ Cool Roof Technology system uses reflective elastomeric coatings sprayed onto the roofing foam to produce a surface that reflects back up to 90% of incoming solar energy. The result is a cooler building and reduced heating and cooling costs.

Minimize Environmental Burden
Bayseal polyurethane roofing foam adheres to almost any surface which means, in most cases, you can replace your roof without tearing off the old one. This will save money as well as keep building materials out of landfills.

LEED Points
A Bayseal foam roof with Bayblock coating can directly gain LEED points in both reducing the urban heat island effect ( SSc7.2) and low-emitting materials (insulation)
(MR2.2). In addition, BaySystems roofing products contribute to LEED points in Insulating (EA2), recycled content (MRc4, MRc3), low-emitting materials (sealant)
(Eqc4.1) and rapidly renewable material (MRc6). An investment in a BaySystems roof is an investment in green building and climate protection.
